Die Erfindung bezieht sich auf ein Verbindungselement für zwei gleichgestaltete, dachförmige Dehnfalten, die sich in schief- oder rechtwinklig aufeinanderstoßenden Wänden eines dichten, dehnfähigen Behälters befinden und in ihrer Längsrichtung aneinanderstoßen.The invention relates to a connecting element for two identical, roof-shaped expansion folds, the walls of a tight, expandable container that meet at an angle or at right angles and abut one another in their longitudinal direction.

Bei der Herstellung von dichten, großen Temperaturunterschieden ausgesetzten Behältern, deren Wände mit dachförmigen Dehnfalten versehen sind, müssen zur Verbindung der Dehnfalten in winklig zueinander stehenden Wänden besondere Verbindungselemente bzw. Eckstücke verwendet werden, deren Nachgiebigkeit wenigstens gleich der maximalen Dehnung der Wände sein muß.When producing dense, large temperature differences exposed containers, the walls of which are provided with roof-shaped expansion folds, must Special connecting elements for connecting the expansion folds in walls at an angle to one another or corner pieces are used whose flexibility is at least equal to the maximum elongation that must be walls.

Der Erfindung liegt die Aufgabe zugrunde, derartige Verbindungselemente durch aufeinanderfol- ts gende Falzvorgänge einstückig herzustellen.The invention is based on the object of successively ts connecting elements of this type Produce low folding processes in one piece.

Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, daß das Verbindungselement aus zwei kongruenten, zusammenhängenden Dreiecken besteht, deren gemeinsame Kante die beiden Endpunkte der »o Firstkanten miteinander verbindet und deren andere Dreieckpunkte in den Schnittpunkten der Grundkanten der Dehnfalten mit der Schnittkante der beiden Wände liegen.According to the invention, this object is achieved in that the connecting element consists of two congruent, connected triangles, the common edge of which is the two endpoints of the »o Connects ridge edges with each other and their other triangle points in the intersection of the base edges of the expansion folds with the cut edge of the two walls.

Diese Eckstücke zeichnen sich dadurch aus, daß as der von aneinanderstoßenden Wänden gebildete Winkel Θ trotz Temperaturänderungen unveränderlich bleibt und seine Elastizität beibehält, die zur Aufnahme der von diesen Temperaturänderungen herrührenden Dehnungen erforderlich ist.These corner pieces are characterized by the fact that the angle Θ formed by abutting walls remains unchanged despite temperature changes and maintains its elasticity, which is necessary to absorb the expansions resulting from these temperature changes.

Die Erfindung wird an Hand eines Ausführungsbeispiels näher erläutert, und zwar zeigt The invention is explained in more detail using an exemplary embodiment, namely shows

F i g. 1 eine schaubildliche Ansicht eines ausschließlich durch Falzen hergestellten Eckstückes,F i g. 1 is a diagrammatic view of a corner piece produced exclusively by folding,

F i g. 3 eine schaubildliche Ansicht eines Eckstücks mitt einer öffnung der Wellung etwa null, wobei gewisse Kanten zusammenfallen.F i g. 3 is a diagrammatic view of a corner piece with an opening in the corrugation approximately zero; whereby certain edges coincide.

In F i g. 1 ist eine Verbindung zweier winklig aufeinanderstehender Bleche mit Wellungen eines konstanten Profils dargestellt. Die Bleche schließen einen zwischen 60 und 180° liegenden Winkel ein, wobei die Stoßkante 3-3' senkrecht zu den Wellungen liegt. Die Wellungen schließen einen Winkel zwischen 0 und 180° ein.In Fig. 1 is a connection of two angled one on top of the other Sheets shown with corrugations of a constant profile. The sheets close you between 60 and 180 °, the abutting edge 3-3 'is perpendicular to the corrugations. The corrugations enclose an angle between 0 and 180 °.

Das Blech erfährt außer der Falzung zur Herstellung der eigentlichen Wellung (mit der Achse x-x') eine doppelte Falzung in dem Abschnitt, in welchem, sich die Wellung befindet, nämlich längs der beiden Linien A-B-C und A-A'-C sowie eine einfache Falzung längs der Kante 3-3'.In addition to the fold for producing the actual corrugation (with the axis x-x '), the sheet metal experiences a double fold in the section in which the corrugation is located, namely along the two lines ABC and A-A'-C as well as one single fold along the 3-3 'edge.

Die durch diese verschiedenen Falzungen erhaltenen Winkel haben solche Werte, daß bei Temperaturschwankungen, welche Änderungen der Höhe der Wellung des eigentlichen Wellensystems zur Folge haben, kein Werkstoff außerhalb der Wände übersteht. Dieses wäre nachteilig, wenn sich die dehnfähige Kammer an einem festen Gebilde abstützt.The angles obtained by these various folds have such values that with temperature fluctuations, which changes in the height of the corrugation of the actual corrugation system result, no material protrudes outside the walls. This would be disadvantageous if the expandable chamber is supported on a solid structure.

Die Werte dieser Winkel sind miteinander durch bestimmte Beziehungen verbunden. Diese Beziehungen können durch Untersuchung des Sonderfalls aufgestellt werden, in welchem der Öffnungswinkel der Wellung null ist, wobei dann die Kante A-A' genau mit der Kante A-x zusammenfällt (Fig. 3).The values of these angles are related to each other by certain relationships. These relationships can be established by examining the special case in which the opening angle of the corrugation is zero, the edge AA 'then exactly coinciding with the edge Ax (FIG. 3).

Der Winkel Θ ist gleich der Summe der durch dieThe angle Θ is equal to the sum of the

Kante A-B begrenzten Winkel xAB und BAx'. Edge AB bounded angles xAB and BAx '.

Wenn die Kante A-A' mit A-x und A-B mit A-C zusammenfällt (Fig. 3), kann geschrieben werden:If the edge AA ' coincides with Ax and AB with AC (Fig. 3), one can write:
